Abstract

Printing machine, such as typewriter, shorthand, teleprinter, in which various characters, such as upper and lower case letters, signs, numbers, music notes, can be printed simultaneously at the same time as the spaces, at different printing points arranged one after the other in the direction of writing, comprising a mobile carriage, a keyboard containing character keys and function keys such as space, box position change, backspace, tab, type bars operated by the character keys, each type bar containing any number of boxes, and any number of characters in each box, the type bars being divided into several groups each having a different printing point, the printing points of the different groups being arranged one after the other in the sense of writing in the order of the groups, that is to say that the first group of type carrier bars imp rhymes at the first printing point, which the second group prints at the second printing point and so on, by actuating a first set of single character keys each a single type bar, characterized in that it comprises a second set of multiple character keys each one activates at least two type bars, some of the single keys and the multiple keys being arranged according to a matrix made up of columns and lines forming between them any angle, with several multiple keys of the same column operating some of the type bars of a first set of type bars that each belong to groups of different type bars, by operating several multiple keys on the same line some of the type bars of a second set of type bars that each belong to groups of type bars that each belong one to groups of bars type carriers different from each other and different from the groups of bars of the first set of type bars, the printing points of all these groups being arranged one behind the other in the direction of writing, in such a way that a multiple key arranged at the intersection of any column and any line activates Simultaneously, type bars belonging to the first set and corresponding to several keys of the column and type bars belonging to the second set and corresponding to several keys of the line, maneuvering this multiple key, therefore, the simultaneous printing of several characters, by actuating some of the simple keys also one of the type bars supported by the multiple keys, and because it also comprises means for selectively modifying the box position of the various groups of type bars, independently of each other, so that Simultaneously print characters from different boxes located on type bars that they belong to different groups, and finally means to generate a carriage shift whose amplitude is proportional to the number of printed characters simultaneously increased by the number of blank spaces located in front of, between or after the printed characters.
